XMLReader is the interface that an XML parser's SAX2 driver must implement. This interface allows an application to set and query features and properties in the parser, to register event handlers for document processing, and to initiate a document parse. All SAX interfaces are assumed to be synchronous: the parse methods must not return until parsing is complete, and readers must wait for an event-handler callback to return before reporting the next event.c C s, t �� | _t �� | _t �� | _t �� | _d S )N) r ZContentHandler� _cont_handlerZ DTDHandler� _dtd_handlerZEntityResolver� _ent_handlerZ ErrorHandler� _err_handler)�self� r �6/opt/alt/python37/lib64/python3.7/xml/sax/xmlreader.py�__init__ s zXMLReader.__init__c C s t d��dS )zAParse an XML document from a system identifier or an InputSource.z This method must be implemented!N)�NotImplementedError)r �sourcer r r �parse s zXMLReader.parsec C s | j S )z#Returns the current ContentHandler.)r )r r r r �getContentHandler" s zXMLReader.getContentHandlerc C s || _ dS )z:Registers a new object to receive document content events.N)r )r r r r r �setContentHandler& s zXMLReader.setContentHandlerc C s | j S )z Returns the current DTD handler.)r )r r r r � getDTDHandler* s zXMLReader.getDTDHandlerc C s || _ dS )z7Register an object to receive basic DTD-related events.N)r )r r r r r � setDTDHandler. s zXMLReader.setDTDHandlerc C s | j S )z#Returns the current EntityResolver.)r )r r r r �getEntityResolver2 s zXMLReader.getEntityResolverc C s || _ dS )z0Register an object to resolve external entities.N)r )r Zresolverr r r �setEntityResolver6 s zXMLReader.setEntityResolverc C s | j S )z!Returns the current ErrorHandler.)r )r r r r �getErrorHandler: s zXMLReader.getErrorHandlerc C s || _ dS )z3Register an object to receive error-message events.N)r )r r r r r �setErrorHandler> s zXMLReader.setErrorHandlerc C s t d��dS )aH Allow an application to set the locale for errors and warnings.

Support for this interface is optional, since not all underlying XML parsers support this functionality. When the parser is instantiated it is ready to begin accepting data from the feed method immediately. After parsing has been finished with a call to close the reset method must be called to make the parser ready to accept new data, either from feed or using the parse method. Note that these methods must _not_ be called during parsing, that is, after parse has been called and before it returns. By default, the class also implements the parse method of the XMLReader interface using the feed, close and reset methods of the IncrementalParser interface as a convenience to SAX 2.0 driver writers.� c C s || _ t�| � d S )N)�_bufsizer r )r �bufsizer r r r o s zIncrementalParser.__init__c C sp ddl m} |�|�}| �|� |�� }|d kr8|�� }|�| j�}x |rb| �|� |�| j�}qFW | � � d S )Nr )�saxutils) � r) Zprepare_input_source� prepareParser�getCharacterStream� getByteStream�readr' �feed�close)r r r) �file�bufferr r r r s s zIncrementalParser.parsec C s t d��dS )a This method gives the raw XML data in the data parameter to the parser and makes it parse the data, emitting the corresponding events.

This class may include information about the public identifier, system identifier, byte stream (possibly with character encoding information) and/or the character stream of an entity. Applications will create objects of this class for use in the XMLReader.parse method and for returning from EntityResolver.resolveEntity. An InputSource belongs to the application, the XMLReader is not allowed to modify InputSource objects passed to it from the application, although it may make copies and modify those.Nc C s" || _ d | _d | _d | _d | _d S )N)�_InputSource__system_id�_InputSource__public_id�_InputSource__encoding�_InputSource__bytefile�_InputSource__charfile)r � system_idr r r r � s zInputSource.__init__c C s || _ dS )z/Sets the public identifier of this InputSource.N)r= )r Z public_idr r r � setPublicId� s zInputSource.setPublicIdc C s | j S )z2Returns the public identifier of this InputSource.)r= )r r r r r9 � s zInputSource.getPublicIdc C s || _ dS )z/Sets the system identifier of this InputSource.N)r< )r rA r r r � setSystemId� s zInputSource.setSystemIdc C s | j S )z2Returns the system identifier of this InputSource.)r< )r r r r r: � s zInputSource.getSystemIdc C s || _ dS )a4 Sets the character encoding of this InputSource.
